Wiring Light Switch

[702enigma]

I want to wire a regular house rocker switch instead of the regular ones that came with my trailer if possible. the original rocker switches are 2 prong and one wire is green with a white stripe and the other is a yellow wire split into another green and white wire with a solid green wire.i doubt the wire colors will help to much but using a voltmeter how do i find hot ground etc. and any advice.

VOM/Multimeter in DC mode the red is positive the black negative, the meter will tell you.

Use a known ground for the black lead and the red one will help you find the hot wire.

Since it is a light switch, none of the wires connected to the old switch are ground or 12 volt negative.
One prong is the 12 volt positive supply (always on) and the other is the light fixture positive (switched). The switch connects the supply to the fixture. As far as the switch is concerned, it does not matter which prong is used for either connection. Just connect the new switch the same as the old switch.
Maybe I missed something in your question. I am sorry if I did.

I wish you good luck and happy trails ahead!

I don't want to be the switch police, but depending on the load, AC is alternating current so it's much easier to break the circuit without an arc since it drops to zero. Depending on the load, an AC only rated switch might weld the contacts, or not.

I was thinking that as I read replies. There is no neutral wire or ground wire being switched, only the hot wire. The wire colors are likely only to identify incoming/always hot, and switched wire.
